Final answer:
Acetic formic anhydride reacts with aniline to produce N-phenylacetamide and formic acid, and with benzyl alcohol to yield benzyl acetate and formic acid. Both reactions are synthesis reactions where new bonds are formed, resulting in amide and ester products, respectively.
Step-by-step explanation:
When acetic formic anhydride reacts with different reagents, specific reaction products are formed due to the reactivity of the anhydride group.
- (i) Aniline: The reaction between acetic formic anhydride and aniline would yield an amide, N-phenylacetamide, and formic acid as a byproduct.
- (ii) Benzyl alcohol: The reaction with benzyl alcohol would produce benzyl acetate and formic acid as the expected products.
The precursors in both reactions are acetic formic anhydride, aniline, and benzyl alcohol. No additional catalysts are typically needed for these reactions, as the anhydride reacts readily with both amines and alcohols. The main byproducts of these reactions would be formic acid when reacting with either aniline or benzyl alcohol.
As for the classification of the reactions:
- The reaction with aniline is a synthesis reaction since an amide bond is formed from the anhydride and the amine, combining two molecules into one.
- The reaction with benzyl alcohol is also a synthesis reaction, creating an ester bond and resulting in the formation of benzyl acetate from the anhydride and alcohol.
